I have a few non LED surefire's that just sit because they EAT batteries so bad.
I have 2 Inova lights that have served me very well, small, LED and well built.
I have about 400 Maglights, big, small, short and tall and 20 different colors. Most all of them are converted to LED with the cheapie kits from China mart. Not the brightest or most "tactical" but they work as a flashlight, a baton, a paperweight, a truck bumper, a boat anchor, a rolling pin, a prybar, a window breaker, nutcracker, winch, fire poker, tire thumper, lynch pin, shovel and a wooden leg.
I also ordered a few lights from dealextreme.com. They are Surefire knockoffs and I don't deny that nor do I feel particularly good about it but I needed a few crazy bright lights and just can't swing a few hundred bucks a peice for them so for about 50 bucks a peice I got monster lights with triple Cree heads that are brighter than auto headlights and I won't have a nervous breakdown if I loose one.
